Introduction

We all have used transactions in one way or the other. In this article, I will show you how you can make use of the SqlTransaction class, which is introduced in ADO.NET 2.0.

What are Transactions?

A transaction is a set of operations in which either all of them are successful or all of them fail to ensure consistency. A simple example of a transaction is when you go to the bank and deposit some amount of money and then transfer your deposited amount to another bank account. In this case, all the operations must be performed for the transaction to be valid. This means that if your amount is not deposited and there is not enough money in your bank account, then there will be an error in transferring the funds. For this reason, we use transactions so that either all the operations are performed or none of them are.

Very clear and simple idea to demonstrate transaction in use. Can be easily modified to see results for other isolation level settings. Nice!

The one that you demonstrated in the example above is not known as ReadOnCommited, it's known as a ReadCommitted.

Please check your finally block.

You should rather call commit directly after you have done the DB operation.
In your case if an error occurs, your finally block will fail because the transaction is not in a usable state at that point.
